(1) where Cmis the mass/volume concentration in mg m−3, Cvis the concentration (v/v) in ppm, M is the gram molecular weight (CO2 = 12 mg/mol, CH4 = 12 mg/mol, N2O = 28 mg/mol), P is the atmospheric pressure, R is the universal gas constant and T is...
where\(\beta\)is the coefficient of the independent variable, and\(W\)is spatial weight matrix.\(\theta\)refers to the spatial lag coefficient of the independent variable, indicating the effect degree by the independent variable in surrounding regions on the dependent variable in the local regio...
A dream comes true: tailor-made polyethercarbonate polyols are synthesised from propylene oxide and CO2. Molecular weight and functionality of these polyethercarbonate polyols are controlled by the use of an appropriate alcohol starter enabling innovative applications as a polymer building block. Interestin...
It required reservoir fluid composition, its molecular weight and reservoir temperature for prediction. This correlation was considered to be more reliable than many others which use only one of the above parameters. It also can predict the effect of contaminants in the injection gas. The equation ...
As liquid CO2 is also used in these simulations, it showed that by using liquid CO2 , the dependency of MMP to molecular weight of hydrocarbon will be decreased and usage of liquid will yield almost same result for all pure hydrocarbons used in this research. 展开 ...

(to keep the concentration ratioMPVP/MM2+ = 5,Mof PVP was calculated based on the molecular weight of its monomer) was added to the above solution and further stirred for 30 min. The mixture was transferred into a 100 mL of Teflon-lined stainless steel autoclave, heated at 160...
molecular weight, and yield of a difunctionalized chain were investigated, where a higher pressure led to a higher yield. The maximum yield was 64% at 23 MPa, and the chain molecular weight (Mw) was 4368 (gr/mol). Additionally, a lower pressure reduced the solubility of materials (particul...
